THRESHING-MACHINE.

Specification of Letters Patent.

lPatented Apr. 5. 12929.

Application filed September 3, 1909. Serial No. 518,092.

To all whom it may concern:

Be it known that I, \VILLIS A. Honmiqcswon'rn, a citizen of the UnitedStates, re siding at Enid, in the county of Garfield and State ofOklahoma, have invented certain new and useful Improvements inThreshingvMachines, of which the following is a speci- I I has is usual.By the particular arrai'igelnent lication.

My invention. relates to threshing niachines of that type cornn'ionlyknown as cylinder machines, and my object is to provide a machineemploying a minimum amount of gearing witha consequent reduction of friction.

A further object of my invention is to provide a threshing cylinder,novel as to its construction, arrangement and operation.

Further obj ects, and the advantages. of my invention will be apparentfrom the following description, in which reference is made to theaccompanying drawings, illustrating my improved CODSLIUCtlOIl, andforming a part of this specification, and in which,

Figure 1 is a side View, partly in section, of a threshing machine,embodying my improvements. Fig. 2 is a transverse section therethroughon line 22 of Fig. 1, and, Fig. 3 is a perspective view of the cylinderremoved, its shaft being broken away.

Referring to these drawings, I provide a threshing cylinder 10, which,as shown in Fig. 1, is mounted longitudinally of the machine, adjacentits rear end, whereas the ordinary cylinders are mounted transversely.The cylinder 10 is secured upon a shaft 11 extendinglongitudinallythrough the entire length of the machine, which shaft projects, at itsrear end, through the rear wall 12, and is provided with a bevel gear13, with which meshes a similar gear 14% driven by a belt 15 from thehand cutter 16 above the feed elevator 17. At the front end of theelevator 17, from whence the material drops to the cylinder 10, there ismounted a feed wheel which the straw is delivered, by the cylinder 10,over the rear wall 2 1 of the concave 25 surrounding said cylinder asusual, said 0011- cave being corrugated and provided with. perforationsthrough which the grain drops upon the grain pan Q6, delivering to thetransverse grain auger 27 at its forward end of the cylinder 10 upon ashaft which extends longitudinally through the entire lcngth'of themachine, however, the usual belts extending longitudinally of the manchine are done away with and better transi mission of power, withreduction of the danger of breakage, obtained. Owing to this arrangementof cylinder 10, however, it is of necessity of different structure fromthe ordinary cylinders which extend transversely. This cylinder has.upon its receiving end, a spiral conveying screw 28 which forces thematerial reaiwvardly to the longitudinal blades 29 upon its-rear end.the centrifugal. force of the cylinder causing the material to be thrownoutwardly againstthe concave 15. This action assists the blades 29 toseparate the grain between themselves and concave 25, the grain beingdisposed of in the ordinary manner as heretofore set forth.

I claim:

In a threshing machine of the character described, the combination of alongitudinal shaft journaled through the ends thereof, a

concave therein around the forward portion of said shaft, a solidthreshing cylinder of uniform diameter throughout its length mountedupon said shaft and located wholly within said concave, said cylinderbeing pro vided with a continuous spiral. feeding vane or flange at itsforward or feed-end, and with straight and separate, spaced,longitudinal threshing blades extending forwardly from its rear end andsecured along its periphery parallel with its axis separate from saidfeeding vane, the rear end of said feeding vane and the forward ends ofsaidthreshing blades, terminating substantially centrally of saidcylinder.

In testimony whereof I allix my signature, in presence of two witnesses.
